Feasibility analysis of letting multi-channel surround sound system into college singing class

Abstract

The multi-channel surround system used for multimedia teaching can bring more powerful auditory effects to the audience, and can fully mobilize students’ interest and enthusiasm in learning. Such as music arrangement, Yunnan musical instruments, the sound characteristics of national music and national musical instruments, and the sound processing knowledge of music processing. You can quickly master basic music arrangement, the sound characteristics of musical instruments, and the knowledge of mixing and processing music. Achieve better teaching results. Most multimedia devices on the market, with the music and sound effects, a high compression mono or stereo transmission. This mono or stereo transmission with a high compression ratio is very low quality. Since audio is far less powerful than visual impact, and the capacity of the disc used to store audio is small, people tend to focus on visual information processing, but ignore the importance of audio. Multi-channel surround sound technology has received more and more attention in the teaching practice of film and television colleges, but it is also affected by various factors such as venue facilities. This has caused bottlenecks in teaching in this field and has greatly affected the teaching effect. This paper designs and constructs a mobile multi-channel surround sound teaching system from a practical perspective. As part of a multimedia teaching device, try to use the best digital surround sound system for today’s audio reproduction. The feasibility of entering the digital surround sound system into the multimedia teaching classroom is analyzed. Better promote students’ correct understanding of audio and use modern high-tech digital technology to spread real art.
